TRUCK @ASTER WHEEL.'

i Application filed February 17, 1922. Serial No. 537,330.

To all who/mat may concern.'

Be it known that we, EMIL A. SMrrH` FIELD and WILLIAM H. NOELTING,citizens 'of the United States, and residents of Evansville county ofVanderburg, and

yState of ndiana, have invented a certain which is primarily adapted to.form a caster 'iti wheel for trucks and the like, wherein a smooth andtrue wheel periphery is desired, together with great strength in thewheel structure.

@ne feature of the invention, in addition to the accomplishment of theforegoing objects, is the construction of a caster wheel from a pair ofidentical plates which are suitably secured together to form said wheelin a manner to insure the greatest strength.

Another feature of the invention consists y in the plural bushinglocking arrangement` of the plates forming the wheel.

Still a further feature of the invention consists in the annular memberassociated with the two plates to form a smooth periphery in thecompleted wheel.

Still a further feature of the invention consists in the constructionof, the plates whereby the same are ribbed for strengthening purposes.

The full naturel of this invention will be understood from 'theaccompanying drawings and the following description and claims.

In the drawings ;Fig.. 1 is a side elevational view ofvone form of wheelembodying the invention. Fig. 2 is a sectional view of the same taken online 2-2 of Fig. /1 and in the direction of the arrows. Fig. 3 is an endview of another form of the invention with a portion broken away to showother parts in section. Fic. 4 is a central sectional view of anotherorm of the invention. Fig. 5 is an end view of another form of theinvention with a portion broken away to show other parts in section. v

In the drawings, 10 indicates a roller bearing construction which may beof any desired type. Said roller bearing construction is receivable by aconcentric locking bushing 11. The concentric bushingl 11 may be ofanydesired diameter and may or may not, as shown in Figs. 2 and 4:,receive said roller bearing and be supported upon a Shaft or spindle.Concentric with said sleeve 11 is another spacing or bushing sleeve 12and associated with said sleeve is a pair of identical cup-shapedplates, each ofk which is provided with a central opening surrounded byan annular groove forming ange 13. The annular Harige 13 receives thespacing bushing 12 and is secured in position by means of the lockingbushing 11 having the ends thereof expanded, as shown in Figs. 2 and t,to retain the bushings and the plates in assembled relation. Each of theplates extends inwardly and angularly and in Fig. 2 said' angularportion la is curved and the pair of plates, when in assembled relation,form an arch construction. Each of the bowl-shaped angular portions isprovided with a radial flange 15 which is perpendicular to the axis 0fthe wheel and the axis of the opening surrounded by the angular groove13. rEhe lianges 15 of both wheel forming plates lare abuttable and inthe present instance are shown apertured as at 16 and secured togetherby bolt and nut means 17 and 18 respectively, the former beingseatablein the registering apertures 16. Each of the Hanges 15 isLprovided with a circumferen- .tial fianges 19 which is concentric withthe sleeves 11 and 12 and the wheel axis. The other edge of thecircumferential flange 19 extends parallel to the flange 15, as at 20,

and as shown in Fig. 3, said ianges may terminate at 120. ln themodification shown in Fig. 2 the flange 20, however, is turned inwardlyat 21 and back upon itself at 21E* to form a bead for reenforcingpurposes.

In order to form a 'smoothv periphery an annular member is providedwhich? herein is indicated by the numeral 22 and in Fig. 2 said annularmember comprises a triangular sectioned bearing ring which is solderedor otherwise secured to the twol wheel forming plates in order to form asmooth periphery for the wheel. In order to provide additional strengtheach of the plates is ribbed as at 23 and said ribbed constructions 23,in thc present invention, also are arch shaped in cross section.

In Fig. 3 the modification disclosed does liti@ shown in ll" ig. 2.Likewise the two wheel i hub portion of the wh'eel forming plates areshown secured together by a rivet 116 instead of b the bolt and nut'means shown in Fi 2. t is likewise to be understood that said plates maybe otherwise secured together without departing from the broaderfeatures of the invention, and one of said means, not shown herein, isby spot welding the same at suitable pointsv 'along the abutting Harigeportions 15.

ln Fig. t another modiiledform of the invention is illustrated and inthis form instead of an arch shaped portion 1d, a triangular shapedportion 11d is shown and instead of providing the trian lar sectionedannular member for orming a smooth peripherythere is provided an annularsleeve member 122 which extends substantially across the peripheralflange portions of the wheel forming plates and is turned over the same,as at 121 to lock the plates together at the abutting peripheral edge.The plates are locked together at the l by the usual pair of concentricbushings. erein it will be noted that the ends of the plates areextended inwardly into abuttable relation at 124. ln the form oftheinventionshom `in Fig. d no other means such as rivets are necessary tosecure the plates together, and

if desired the spacing bushing may likewise be omitted. l l v lin Fig. 5a modified form of the invenneeaeei of plates having rim for-mingyflanges and central openings adapted to register, groove forming flangesconcentric with the openings, a spacing sleeve having its edges seatvable in said grooves, a second sleeve concentric vwithin the iirstsleeve with itsedges securing the plates and spacing` sleeve together atthe hub portion, and an annular member associated with the rim formingflanges to form a smooth wheel rim.

2. ln a wheel, the combination with a pair of complementary plateshaving central openings adapted to register, and ra dial portions, and acentral pair of concentric sleeves, of an annular concentric grooveforming projection curved in radial cross section and projectingoutwardly from each plate at the opening and defining the same, saidouter sleeve being seatable in the grooves of said plates, and the innersleeve locking the same together.
